To all whom t may concern.'

Be it known that l, WALTER J. BEACH, a citizen of the United States,residing at Minneapolis, in the county of Uttawa and State of Kansas,have invented certainnew and useful Improvements in WalLlPaper Fastingand Trimming Machines; and ll do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

rlhis invention relates to-improvements in wall paper pasting andtrimming machines of that character in which the trimming and pasting isaccomplished simultaneously as the paper is drawn through the device.

The principal object of the invention is to provide a device of thischaracter having a paste receptacle in which a buoyant paste applyingmember is disposed, the shape of the parts being such that the machinemay be operated until all of the paste has been used out of thereceptacle.

An additional object is to provide a pressure roller in connection withthe buoyant paste applying member which holds the pa-v per in contactwith themember, said roller being loosely mounted in suitable bearingsso that it may be moved vertically by the buoyancy of the paste applyingmember.

A further object is to provide an improved cutter for trimming the wallpaper, which may be moved into various positions so as to remove more orless of the selvage from the paper.

A still further object is to provide a simply constructed device forevenly distributing the paste upon the paper, said device beingadjustable so as to allow a greater or lesser amount of paste to beretained on the paper, depending upon the place where the latter is tokbe used.

With these and many other objects in view, my invention consists of thenovel features of construction and the combination and arrangement ofparts which will be hereinafter more particularly described and claimed.

ln the accompanying drawings: Figli-re l` cal transverse sections takenrespectively on the planes of the lines 5--5 and 6-6 of Fig. 1; Fig. 7is a fragmentary view showing one of the slides for supporting one endof the pressure roller, said slides being in lowered position; Fig. 8isa view similar to Fig. 7 but showing said slides in elevated positlon;Fig. 9 is a detail transverse sect1on showlng one of the guides forreceiving one of the trunnions of the paste applying roll; Fig. 10 is adetail vertical section on the plane of the line 10-10 of Fig. 9; Fig.1,1 .is a longitudinal section through one end of the cutter roll; Fig.12 is a detail per spective view of one end of the paper roll carrierarranged adjacent its operating free edges of these portions are bentinwardly toward each other as at 6, and then downwardly as at .7. Theupper edges of the end walls 3 are also bent-inwardly and downwardly asshown at 8, in order to prevent the paste which is disposed in theVtrough from spilling therefrom.

Within the trough 2 a floatable paste applying roll 9 is disposed.'llrunnions 1() are formed on the opposite closed ends of this roll andare disposed in vertical guides 11, the latter being formed fromchannel-shaped strips whose lower ends are soldered or otherwise securedto the bottom of the trough while their upper ends are similarlyconnected to the inwardly and downwardly extending portions 8. Ilhesechanneled strips have their lower portions pressed together to formseats 12 in which the trunnions 10 rest when the trough is empty, theperiphery of the roll 9 being slightly spaced from the surface of thetrough 2 when said trunnions are in this position. As the wall paper isdrawnthrough the machine it will be forced to engage the roll 9 in amanner to be later set forth, thus causing it to rotate and apply thepastel which it gathers from the supply in the trough.V It is obviousthat when the trough is filled with paste the roll 9 will be spaced aconsiderable distance above the bottom of the former, but as the pasterecedes the roll will gradually lower, the trunnions thereof moving inthe vertical guides 11.

The part of the machine which is used to feed the wall paper to thepaste applying yroll is mounted in a frame which consists of a pair ofend members 13 which are formed approximately inverted U-shape,connected by a pair of longitudinally extending connecting bars 14 whichare fixed to the end members 13 at their opposite edges. This frame, aswill be seen from the foregoing, is substantially rectangular in planview and is of a size similar to the dimensions of the top of the pastecontainer. One end of the frame is hinged by one of the end members 13to the top of one of the end walls 3 by means of the hinges 15. Theother end member 13 carries a hook 16 for engagement with an eye 17 onthe adjacent end wall 3 so that the frame and the paste container may belocked together. By hinging the frame to the paste container, the formermay be raised so as to readily lill the trough with paste, or to threadthe paper between the various feeding rolls.

The top or apex of each of the end members 13 is vertically slotted asshown at 18 to form bearings for the opposite ends of a paper rollcarrier 19 on which the roll or wall paper as it comes from the factory1s disposed, this paperV roll being designated by the numeral 20. As iswell known, there 1s a small opening through the center of the.

paper roll, and in this I insert a shaft 21, one end of said shafthaving a pair of collars `22 ailixed thereon, the distance betweenythese collars being substantially equal to the thickness of one of theend members. When the shaft is placed in the bearings formed by theslots 18, these collars rest one on each side of one of the said endmembers. The opposite endy is reduced and squared as shown at 23 and isadapted to be disposed in a socket formed in the end of a stub shaft 24,the latter projecting from the hub between the pulley wheel 25. Slidablymounted on the shaft 21 is a pair of disks 26 and 26', said disks havingsleeves 27 extending from the outer sides thereof as clearly shown inFigs. l and 2. The sleeves carry nuts 28 in which thumb screws 29 aredisposed, said thumb screws extending through openin s in the sleeves 27so as to engage the sha 21, thereby allowing the disks 26 and 26 to beheld in adjusted position thereon. The disk 26 carries on its inner facean v:additional sleeve 30, from the periphery of which a plurality,preferably four, wings 31 extend, these wings tapering upwardly fromthefree end of the sleeve 30 to the disk 26. This last mentionedconstruction is designed to be forced into engagement with the adjacentportions of the paper roll 2O when the shaft 21 has been insertedthrough the opening therein, thus the paper roll is held againstrotation on said shaft and caused to move therewith. The disks 26 and 26are designed to engage the opposite ends of the paper roll 20, the disk26 holding the latter into engagement with the wings 31. Since each ofthe disks is movable, various lengths of paper rolls may be operatedupon in this machine, and various widths of paper may be removed fromthe edges of the roll by the rotary cutter which will later bedescribed.

After the roll of wall paper has been properly positioned upon itscarrier 19, the end of the paper is passed over what will be termed forthe sake of convenience, a cutter roll 32, and then threaded under aguide roller 33. The cutter roll consists of two separable parts, a mainportion 34 and a short section 34,'the former having a long trunnion 35extending from one end which is disposed in a bearing formed in one ofthe end members 13. The other end of the main portion 34 has a sleeve 36extending therefrom and is designed to receive one end of the section34', the opposite end of this last mentioned portion having a shaft 37which is rotatably mounted in suitable bearings 38 disposed on thehorizontal portion 39 of a suitable bracket 40. This bracket issupported by one of the end members 13. The section 34 is formed of apair of short cylinders lixed to said shaft 37, the same extendingtherethrough as shown in Fig. 11. The cylinders are spaced apart as at47 and their adjacent ends are open. The horizontal part 39 of thisbracket 40 also has an additional set of bearings 41 disposed theres onin which a shaft 42 is rotatably mounted. This shaft carriesintermediate the bearings 41 a small pulley 43 which is disposed in thesame plane as the large pulley 25 hereinbefore mentioned. A suitablebelt 44 is trained over these pulleys '25 and 43 so that when the paperroll is rotated its motion will be transmitted to the small pulley 43which, being fixed to the shaft 42, causes the latter to revolve andoperate a rotary disk cutter 45. This cutter is preferably toothed andis held between a pair of clamping members 46, the latter being circularand adapted to engage the section 34' of the cutter roll 34. Since theseclamping members 46 engage the portion 34', the .periphery of the diskcutter 45 is disposed within the space 47 between the ends of thecylinders forming the section 34'. The paper from the roll 20 isdesigned to be threaded between the cutter roll 32 and the rotary cutterso that the usual selvage may be removed, and as the roll of paper isadjusted laterally upon its carrier, various amounts Lamme may beremoved from the edge of the paper as it is moved `into engagement withthe cutter. A suitable deflecting guard 48 guides the severed strips ofpaper and prevents them from entering the trough con- Itaining thepaste.y

The guide roller 33 hereinbefore mentioned has trunnions 49 extendingfrom its opposite ends which are rotatably mounted in said end members13 adjacent one outer edge thereof. After the wall paper' has beencarried beneath this guide roller 33 its back comes into engagement withthe paste applying roll 9 in order that a quantity of paste from thetrough 2 may be applied. A weighted pressure roll 50 holds the paperinto engagement with the paste applying roll so that the entire surfaceof the paper will be thoroughly coated with'paste. This pressure rollconsists of a cylinder closed at 1ts ends and having a shaft 51extending transversely therethrough, the opposite ends of this shaftbeing extended beyond the ends of thel cylinder and disposed invertically alined bearings 51. One end of the cylinder of the pressureroll has a sleeve 53 fixed thereto, said sleeve carrying a set screw 54in order that the cylinder may be adjusted and held in various positionsupon the shaft 51. This adjustability is necessary in order .to shiftthe roll relative to the paper roll.

The elongated bearings 51 in which the ends of the pressure roller aremounted, are carried by the lower ends of vertically movable slides 55,two of which are provided,

one for each of the end members 13. 'These slides are movable verticallyin channeled guides 56 which are soldered or otherwise secured to saidend members 13. A handle 57 is formed on the upper end of each of theslides so as to readily permit the same to be raised, these handlesalsoforming stops to limit the downward movement. By this arrangementthe pressure roller may be-raised out of engagement with the pasteapplying roll so that the wall paper may be more readily passed throughthemachine, particularly when a new supply of paper is lbeing inserted.Tn order to hold the slides in their raised positions so as to retainthe pressure roller spaced above the paste applying roll, stops 58 areformed on the slides. Any number of these stops may be provided,although only one is shown4 in the present instance. The stops areformed by reducing the lower portions of the slides in order to provideshoulders. As hereinbefore mentioned, the paste applying roll 9 isbuoyant and rises and falls with the varying amounts of paste within thetrough. This movement is permitted by the vertical guides 11, and it 1sobvious that when the roll rises in the trough it will also carry withit the pressure roller if the latter is inbe seen that when the roll ofpaper has been adjusted upon the carrier 19, the end of the former ispassed over the cutter roll beneath the first guide roller 33, and thenbetween the pressure roll and paste applying roll, after which it goesunder the second guide roller 59, whereupon it is ready to be appliedtothe wall or ceiling of the room to be papered. Tn starting the paperthrough the machine beneath the various rolls or rollers, the frame islpreferably tilted back as hereinbefore described.

Tn certain instances, particularly when the wall paper is to beappliedto the ceiling, a thicker coat of paste is necessary to cause thepaper to adhere than when it is to be applied to the side walls.Therefore,

in order to regulate the amount of paste to be left on the back of thepaper when the same is passed over the paste applyingroll,`

I provide what will be termed a paste distributer, this consisting of asubstantially l shaped plate' 60 pivoted to move toward or away from thesecond guide roller 59.

The plate is fixed by its long arm to a shaft 62 which is journaled inbearings formed in the end walls 3 of the paste container, the short armbeing bent upon itself to provide a contact member ,63 which engages thepaper and removes more orless of the paste which has been appliedthereto. This distributer is regulated by means of a handle or lever 64pivoted to one end of the shaft 62 so as to move laterally, the handlebeing adapted to engage any one of a number of ratchet teeth 65- formedon a ratchet plate 66, the latter being xed to the outer side of one ofthe end walls 3. Thus it will be seen that when the handle 64 is movedupwardly or downwardly the distributer is moved in a ,correspondingdirection to dispose lthe contact edge 63 toward or away from the secondguide roller 59.

Tn addition to the rotary cutter herein- Abefore mentioned which isfixed relative to the frameupon which it is mounted, a slidable cutter67 is provided. This last mentioned cutter consists of a. sleeve 68which is slidably and rotatably mounted upon a longitudinally extendingshaft 69 secured by its opposite ends to the top of the paste container,an arm 70 fixed to said sleeve, and a head 71 in which the cuthing blade72 is removably. secured. The sleeve substantially U-shaped in crosssection.

This last mentioned adjustable cutterv 67 may be used similarly to therotary cutter or trimmer for cutting the selvages of the edges of theWall paper, but it is primarily used for splitting a Width of paper fromthe main portion of the roll for use in corners of rooms or other placesWhere only a portion of a width of the strip is needed. Inasmuch as therotary cutter or trimmer 45 is not adjustable it is necessary to adjustthe vvarious rolls of paper to be trimmed upon their carrier 19. Afterthis adjustment has been made so as to remove the selvage from the edgeof the paper adjacent the rotary cutter, the slidable cutter 67 may bemoved on its shaft 69 until it is brought to the proper position.

From the foregoing description, taken in connection with theaccompanying drawings, itis obvious that I have produced a very simpleand compact wall paper paster and trimmer in which the severaloperations of pasting and trimming may be simultaneously accomplished.The idea of providing a floatable or buoyant paste applying roll will befound to be extremely important, inasmuch as the paste trough will notbe required to be filled so frequently because of the fact that all ofthe paste therein is used up before the machine becomes inoperative.

I claim:

1. In a device of the class described, a paste container, a pasteapplyin roll in said container, a frame disposed a ove said container, apaper carrier mounted in Said frame, vertical channeled guides-securedto each opposite end of said frame, a vertically movable slide disposedin each of said guides, and a pressure roll journaledin said slides andnormally engaging said paste applying roll, each of said slides having astop adapted to engage the top of said guides when the former areraised, whereby said pressure roll may be spaced from the paste applyingroll. v
